iPhone spurs improvements in other mobiles

Concepts embodied in the iPhone are making their way into other, more open devices. "A rising tide floats all boats," it's said, and Apple's innovations are spreading out to benefit users of other devices.

Some hardy Brazilian inventors wanted to see if there was a benefit to the iPhone's virtual keyboard, so without ever having touched an iPhone (which doesn't work there), they created an analogous keyboard for the Nokia N800 Internet tablet.
